Subject: net: add inline function skb_csum_is_sctp

[ Upstream commit fa82117010430aff2ce86400f7328f55a31b48a6 ]

This patch is to define a inline function skb_csum_is_sctp(), and
also replace all places where it checks if it's a SCTP CSUM skb.
This function would be used later in many networking drivers in
the following patches.
